The National Weather Service in Tucson has issued a Red Flag Warning for Tucson and the Bighorn Fire area from noon to 8 p.m. MST Sunday and from noon to 8 p.m. MST Monday. The prediction is for strong winds, low humidity, and very high fire danger. The wind is expected to be out of the southwest at 15 to 25 mph with gusts to 35 mph Sunday, and on Monday, southwest at 15 to 20 mph with gusts between 35 and 40 mph. The relative humidity will be 10 to 17 percent in the valleys and 13 to 21 percent in the mountains.

From the Incident Management Team on Saturday:

“Friday night, burnout operations south of Davis Spring Road and 4 miles west of Redington were conducted to reduce the risk of eastward fire spread. Aerial ignition operations were conducted near Palisade Canyon and Green Mountain to improve firelines and reduce the risk of uncontrolled fire reaching the Catalina Highway. East of Saddlebrook a firing operation improved firelines. Holding, mop up and structure protection was the focus in Summerhaven, Willow Canyon, and Saddlebrook. Biosphere, Oracle, and Sabino Canyon were in patrol status.

“Saturday’s Activities: Crews will hold and improve line near Willow Canyon, Palisade Canyon, Green Mountain, and south of the Davis Spring Road. Hotshot crews will build fireline on the south side of Green Mountain. A hand crew will work to extinguish a hotspot approximately three miles northeast of Catalina State Park.  East of the fire, construction will continue on contingency lines by connecting to existing road systems. Structure protection will be in place for Saddlebrook and along the Catalina Highway.Initial attack resources are pre-positioned around the fire.”

A mapping flight Friday night determined that the Bighorn Fire had burned 95,225 acres, a 24-hour increase of over 7,000 acres.

Mine Draw Fire being fought 6 miles south of Mount Rushmore

In the Black Hills of South Dakota

(UPDATED at 3:36 p.m. MDT June 25, 2020)

Jim Strain who took this photo from the Fairburn, SD area, said it looked like this storm cell was over the Mine Draw Fire. Posted by Jim at 1:04 p.m. MDT June 25, 2020.

Custer State Park announced that as of 2 p.m. today the Mine Draw Fire is 100 percent contained. We are waiting to hear if the Governor has declared it officially contained.

That was around the time that a very large thunderstorm cell was centered over the fire. As of 3:18 p.m. 0.25″ of rain had been measured at the Custer State Park airport.

(UPDATED at 12:14 p.m. MDT June 25, 2020)

The only official information available today about the Mine Draw Fire was issued by the South Dakota Governor’s office. The update said the  fire has burned 60 acres, which is a decrease from the Wednesday afternoon estimate of 150 acres.

The fire was reported at 11:19 a.m. June 24 in Custer State Park six miles south of Mount Rushmore.

The statement from the Governor’s office said that in addition to the hand crews and fire engines, there are two Type 1 helicopters and one air attack plane on scene for a total of 117 personnel. Yesterday three Type 1 Hotshot crews were at the fire or en route.

A resident near the fire said that last night the wind in the fire area was calm and there was not much smoke. Another person who was farther way could clearly see the smoke column yesterday but early this morning none was visible.

The weather station at the Custer State Park airport recorded a maximum relative humidity overnight of 70 percent. At 11:18 a.m. MDT today it had dropped to 39 percent, the temperature was 83, and the wind was 12 mph out of the northeast gusting up to 21 mph. The forecast for the fire area at 5 p.m. calls for the temperature going down to 73, humidity 54 percent, and increasing cloud cover with showers and thunderstorms likely.

With the overnight conditions, the forecast, and the resources on hand, the firefighters could have a good chance of stopping the spread of the 60-acre fire today.


(UPDATED at 8:15 p.m. MDT June 24, 2020)

Two additional hotshot crews are en route to the Mine Draw Fire east of Custer, South Dakota — the Roosevelt Hotshots from Colorado and the Wyoming Hotshots.

The fire is half a mile north of the Legion Lake Fire that burned 54,000 acres in December, 2017.

The South Dakota Governor’s senior advisor and policy director, Maggie Seidel, said at 8:15 p.m. MDT Wednesday that the fire has burned 150 acres.

The customary system for distributing information about wildfires in the Black Hills is with local agency information officers coordinated through the Great Plains Interagency Dispatch Center. But for this fire, information is being controlled by Governor Kristi Noem’s office.

On Tuesday structure protection and containment work supported by helicopter bucket drops focused around Mt. Lemmon, Summerhaven, and Willow Canyon. Low-intensity firing operations removed pockets of unburned fuels in these areas. Aerial firing operations were conducted south of Oracle. The efforts near Oracle Ridge and Rice Peak are intended to reduce the risk of uncontrolled fire growth to the north in the coming days.

Evacuations are in effect. For more information visit pima.gov/bighorn or pinalcountyaz.gov/emergencymanagement

Resources assigned to the fire Tuesday included 20 hand crews, 81 fire engines, 6 dozers, 19 water tenders, and 10 helicopters for a total of 876 personnel. The number of personnel assigned has decreased by 112 since Monday. There have been 4 minor injuries.
